What You Need to Know About the 2019 RAM 1500 Battery?
The 2019 RAM 1500 uses a Group H7 AGM (Absorbent Glass Mat) battery with 800 cold-cranking amps (CCA) and a 36-month warranty. Located under the hood near the driver’s side, it powers advanced features like start-stop technology. Regular maintenance and voltage checks are critical to avoid failures, especially in extreme temperatures.
Where Is the Battery Located in a 2019 RAM 1500?
The battery is positioned under the hood on the driver’s side, secured by a hold-down bracket. Unlike older models, the 2019 RAM 1500 doesn’t relocate the battery for trim variations. Access requires removing a plastic cover and loosening the bracket. Note: Dual-battery configurations exist in some diesel models, but gas engines use a single battery.
What Are the Signs of a Failing Battery in a 2019 RAM 1500?
Key symptoms include slow engine cranking, flickering headlights, frequent jump-starts, or warning messages like “Battery Saver On.” Test voltage with a multimeter: readings below 12.4V indicate low charge. AGM batteries may fail suddenly due to their deep-cycle design. Extreme heat accelerates degradation, reducing lifespan to 3–5 years.
How Do You Replace the 2019 RAM 1500 Battery?
Steps: 1) Turn off ignition and open hood. 2) Disconnect negative (black) then positive (red) terminals. 3) Remove hold-down bracket. 4) Lift out old battery. 5) Install new AGM H7 battery. 6) Reconnect positive first, then negative. 7) Reset the Battery Monitoring System via the dashboard menu to prevent charging errors.
Why Use an AGM Battery in the 2019 RAM 1500?
AGM batteries handle the high electrical demands of start-stop systems and onboard computers. They’re spill-proof, vibration-resistant, and recharge faster than traditional lead-acid batteries. Using a non-AGM battery may trigger dashboard warnings or reduce fuel efficiency. OEM brands like Mopar or aftermarket options like Odyssey Extreme are recommended.
AGM technology uses fiberglass separators to contain electrolytes, allowing for faster energy delivery during engine starts. This design also minimizes sulfation, a common cause of battery failure in vehicles with irregular usage patterns. For RAM 1500 owners adding aftermarket accessories (winches, lighting systems), AGM batteries provide 20% more cyclic durability than flooded batteries. The table below compares key specifications:
| Feature | AGM Battery | Standard Lead-Acid |
|---|---|---|
| Recharge Rate | 5x Faster | Standard |
| Vibration Resistance | High | Moderate |
| Ideal Temperature Range | -40°F to 176°F | 32°F to 104°F |
How Does Cold Weather Affect the 2019 RAM 1500 Battery?
Cold temperatures thicken engine oil, increasing cranking effort. AGM batteries lose up to 30% CCA at 0°F. Prevent failure by parking in a garage, using a battery blanket, or maintaining a full charge. Diesel models with dual batteries require both units to be replaced simultaneously to avoid imbalance.
In sub-freezing conditions, chemical reactions within the battery slow down, reducing its effective capacity. A fully charged AGM battery at 80°F delivering 800 CCA might only provide 560 CCA at 0°F. Owners in cold climates should consider these precautions:
- Use a maintenance charger during extended storage
- Activate the engine block heater (if equipped) 2 hours before starting
- Limit short trips that prevent full recharge
What Are the Warranty Considerations for a Replacement Battery?
Most AGM batteries include a 3-year free replacement period. Pro-rated warranties cover partial costs afterward. Keep receipts and note installation dates. Warranties void if the battery is improperly stored, jump-started excessively, or installed in non-compatible vehicles. OEM batteries may require dealership registration for full coverage.
Expert Views
“The 2019 RAM 1500’s electrical system relies heavily on battery health. AGM technology isn’t optional—it’s engineered for modern power demands. Owners should test voltage quarterly and avoid aftermarket accessories that drain power when idle. Always reset the Battery Monitoring System after replacement; skipping this can cause premature alternator wear.” — Automotive Electrical Systems Specialist
Conclusion
The 2019 RAM 1500’s battery is integral to its performance and technology features. Proactive maintenance, using AGM replacements, and understanding warranty terms ensure reliability. Address warning signs immediately and prioritize OEM-compatible batteries to avoid system errors.
FAQs
- Can I Use a Regular Battery Instead of AGM in My 2019 RAM 1500?
- No. The truck’s charging system is calibrated for AGM batteries. Non-AGM units may overcharge, leak, or fail prematurely.
- How Often Should I Check the Battery Voltage?
- Test every 3 months or before long trips. Ideal voltage is 12.6–12.8V when idle.
- Does the 2019 RAM 1500 Have a Battery Management System?
- Yes. It monitors charge levels, adjusts alternator output, and can disable non-essential features to conserve power.
